If you are using windows 32 bit Operating system, Then it will only recognize 4 gigs and will show around 3.2 -> 3.5 as usable.
To fully use 4 or more gigs of ram you need to switch to 64 Bit OS.

If you are using a 64 bit OS:
One check your BIOS to verify that it shows up in bios and if it does then to see if there is a setting for using 4 gigs
Two, if it does not show up in bios, try reseating memory modules.

Even if you are using a 64 bit OS, if your motherboard does not support higher than 4gb then you can't force it to take more.

Give your model number of your motherboard.

^ Yes, and
Since you are using a 64 bit OS:
One check your BIOS to verify that it shows up in bios and if it does then to see if there is a setting for using 4 gigs

^ even if it shows up in BIOS, that doesn't mean that your system will actually use all that ram in a 64 bit OS, that is just the reading of actual ram installed, not what will be acceptable for the system.

Start > Control Panel > System

That page will show you your installed ram and what is actually being used.
Mine says 4.00gb (3.00gb usable)


Just give us your Motherboard specs to clarify, also your CPU as it may require FSB Parity.
